Methods of Fertilizer Application. https://cststudy.blogspot.com/ B.Sc.Ag. (Hons) Part-I  Methods of Fertilizer Application Fertilizer recovery is greatly influenced by method of its application. Method of application varies according to the spacing of crop, type of fertilizer material, time of application, etc. A brief account of these points could be explained as under : A.Method of application of solid fertilizer materials Solid materials may be applied in following ways: 1. Broadcasting Even and uniform spreading of dry solid fertilizers by hand or spreader over the entire field before or after sowing of the crop is termed as broadcasting. Well decomposed FYM, compost, oil cake, bone meal, urea, superphosphate and lime are applied by this method. Advantages This method is easy, less time taking, cheap and more convenient to the farmers. This method proves effective- i.            ...
